Can someone shed some light on what exactly has been preventing people from making this 3.5L big bore duratec before? I see nautilus performance is putting one out now.. I'm guessing worries of a cracked block, but wouldnt some reinforced sleeves help alot with that(ala what nautilus is doing obviously).. I'm pretty interested in trying to build my own 3.5+l duratec and get one of the faster naturally aspirated contours around hopefully
Some insight would be appreciated!
